The cylindrical portion 0 of the shell receives the wheel, I a tubular shell, and an annular flange plate.

not shown. The outer end of the shell'is enlarged at S to receive the raceway Dfor ion entering and fitting said shell, the said the bearing-balls E. Said balls arereceived in a groove in theeollar F on the axlefir The end of the axle is threaded to receive nut H. The usual'capI covering the ball-- bearing and end of the hub is provided.

J is a flange plate, againstwhich the wheel nave bears when in place on the cylin-- drical portion G of the hub. Said flange has an outwardly struck up projection K which fits closely in the cylindrical portion C of the hub. Said projection is internally concave, and receives the race-way L for the bearing-balls M. Said balls are supported in a grooved collar N on axle Gr. A grooved ring 0 containing grease-retaining material may also be fitted on the collar The shell is electrically welded at its inner circumferential edge to a ribP on the outer side of flange J, and also, if desired, to the projection K at a number of spots, as Q.
